Except for the restrictions on content, mail sent at nonprofit rates looks just like regular Standard Mail. The only difference is the required marking for nonprofit mail. NONPROFIT ORGANIZATION, NONPROFIT ORG, or NONPROFIT must appear:

• In the imprint indicia.

• On a nonprofit precanceled stamp.

• As part of the meter impression.

• Printed on the mailpiece, adjacent to the postage area.

In addition, the name and address of the nonprofit organization MUST be shown, either on the outside of the mailpiece or in a prominent place on the contents.

Nonprofit mail is sorted and prepared the same way as regular Standard Mail. Click here to learn how to (sort and prepare Standard Mail).

TIP
If a return address is included on the mailpiece, then the address must be that of the authorized organization.
